Safety instructions

For your safety, the information in this manual must be followed to minimize the risk of fire or explosion, electric shock, or to prevent property damage, personal injury, or death.

This symbol will alert you to any product detail or operation that could lead to a safety hazard if the instructions in the manual are not followed properly.

Warning :

Caution :

If not followed, it can cause death or major injury to the user.

This symbol will alert you to the possibility of improper use that may result in

damage. Read instructions to avoid damage or injury.

This appliance has a polarized plug(one blade is wider than the other). To reduce the risk of electric shock, this plug is intended to fit in a polarized outlet only one way. If the plug does not fit fully in the outlet, reverse the plug. If it still does not fit, contact a qualified electrician. Do not attempt to defeat this safety feature.

Warning

When Installation

• If the power cord becomes worn or damaged, the cord should only be replaced by a qualified service technician using genuine replacement parts.

• Do not plug other appliances into the same outlet. Overloading of any outlet can cause a fire or create an electrical shock hazard.

• Do not remove the round grounding plug prong from the plug.

• Do not operate this or any electrical appliance when you smell gas.

• Do not operate with wet hands or in a damp environment.

• Do not disassemble or modify the air purifier or the power cord.

• Do not use this or any appliance near flammable gases or liquids, liquids or other combustibles such as gasoline, benzene, thinner, etc.

• If you hear abnormal sounds or smell smoke, immediately unplug your unit and the unit checked by a qualified service technician.

• Make sure the unit and cord are positioned where it does not create a tipping hazard. Do not roll heavy furniture over the top of the cord.

• Do not use near open flames.

• Keep this product out of the direct ray of the sun or other heat sources. Do not use the unit near water sources that could allow moisture to enter the unit. Overheating and/or water infiltration could lead to a fire or a shock hazard and could result in failure to the product.

Safety instructions

Operation

• Make sure the power cord is plugged firmly and completely into the outlet.

• Do not operate with wet hands.

• If the power cord ever becomes frayed or damaged, do not attempt to repair. The cord should be replaced by a qualified technician.

• Never pull the power plug away from the outlet by pulling on the wire. Always grasp the cord by the receptacle end.

• Do not install a place where there are much industrial Oil dust or metallic dust. It may cause fire and failure of product.

• When the power code is damaged, it should be repaired by the qualified person to prevent any risk. Otherwise, it may cause electric shock, fire or failure of product.

• Never pour or allow water to run onto or into the unit. It could damage internal components and create a shock and fire hazard.

• Keep objects such as curtains away from the air opening in the unit. The openings must be free from obstruction for the unit to work efficiently.

• Do not run power cords under carpeting or other coverings which could fray the cord and expose the wires. Frayed cords are a shock and fire hazard.

• Do not place the power cord or unit near a heater, radiator, or any other heat source.

• This unit is not designed for use by children. Children should be supervised to ensure that they do not play with or climb on the unit.

• Do not use your unit to remove hair spray and insecticides from a room. These chemicals not only clog the filters but could damage the unit.

• Secure the unit to prevent it from rolling on smooth floors. When moving the unit, insure that the power cord is unplugged from the wall.

• Do not move the unit by pulling or pushing on the front panel.

• Do not use the top of the unit for storage. Keep liquids away from the top of the unit.

• Other than cleaning and replacing the filters, there are no user replaceable components in your unit. Serve of this should be referred to a qualified service technician.

• Do not apply pressure to the front panel of the unit.

Caution

When Installation

• When using the unit, maintain a distance of at least 3 feet between the unit and any television or audio product.

• Avoid installing the unit in direct sunlight and never operate the unit near or around open flames or other heat sources.

• Never use your unit to remove toxic gasses such as Carbon Monoxide, Natural or Liquefied Petroleum Gasses.

•

Do not use your unit to remove food odors while cooking. Airborne oils that are released during cooking will clog the filters. Wait until cooking is complete before operating your unit.

• Install the unit on a stable, flat surface.

• Maintain a minimum distance of 5 feet from any heat producing light source. For proper ventilation, maintain a distance of 6 inches or more from a wall.

• Do not use except AC 120V.

Otherwise, it may cause fire or electrical shock.

• This unit is not designed to remove combustion by products such as those produced by open flame burners. Toxic substances such as carbon monoxide should be ventilated from the room by either using an exhaust fan or by opening a window.

• Your unit is not designed to be used in moving vehicles such as cars, RV's or boats.

• Clean with a soft cloth and mild detergent. Filter should be cleaned monthly.

• Do not start or stop operation by plugging or unplugging the power cord.

• Always turn off and unplug the unit when it will not be used for extended periods of time. This conserves energy and reduces the chance of accidents.

• Clean filters on a regular basis. Improper filter maintenance can cause premature failure of the product.

• Warn the user to unplug or disconnect the appliance from the power supply before servicing.

• A damaged filter can create an electrical hazard.

• If a humidifier is used in the same room as your unit, keep the humidifier a safe distance away from the humidifier could clog the filters and create an electrical shock hazard.

• Do not use your unit to remove food odors while cooking. Airborne oils that are released during cooking will clog the filters. Wait until cooking is completed before operating your unit.

• Do not open the front panel during the operation of the product. Opening the front panel stops the operation.

• After washing your filters, make sure they are completely dry before reinserting them into the unit. Do not run your unit with wet filters.

Terminology

1. VOCs (Volatile organic compounds)

(1) What is VOCs?

Carcinogenic substances that cause allergies or respiratory ailments, such as a paint, adhesives, spray, construction materials, wax, carpet, and etc. Unlike the general perception that only cheap construction materials emit VOCs, high quality new constructions may also emit VOCs. It may stay remained in a closet or inside of furniture even after several years.

Filters Introduction

(1) Nano silver Pre-Filter

One filter performs antibiotic treatment, anti mold treatment, and dust removal, providing a purified air.

(2) Washable HEPA Filter

HEPA filter polluted by acarid deadbody, pollen, small dust and float mildew, animal bodyhair etc. can be washed.

(3) Washable Deodorization Filter

This filter was processed with activation treatment for stronger adsorption function (characteristic of charcoal). This deodorization filter has higher level of negative ion, minerals, far infrared lays generation ability than charcoal.
